A Floral Park man was arrested Tuesday on charges of producing child pornography after FBI agents raided his home and found videotapes of him "engaging in sexual contact with boys who appear to be as young as 15 to 17 years old," according to court papers.

Vincent Calamia, 48, was held without bail as a danger to the community late Tuesday afternoon in federal District Court in Central Islip, officials said.

Authorities said they are investigating allegations that some of the victims were drugged before they were videotaped.

A conviction on a charge of production of child pornography carries a mandatory minimum sentence of 15 years in prison and a maximum of 30 years for each child involved in the crime, said Robert Nardoza, a spokesman for the U.S. district attorney's office for the Eastern District of New York.

In court papers, prosecutor Lara Treinis-Gatz said the investigation by the FBI, and Nassau and Suffolk police began in June, when a person identified only as John Doe told them that Calamia had sexually assaulted "him and several of his acquaintances regularly over the past several years, beginning when [he] was less than age of 18."

Further, the unnamed person said that Calamia had videotaped sex acts between them and told him he did so with other boys younger than 18 as well, the papers said.

The papers said Calamia's child pornography activities began in 2005 and had been ongoing until his arrest. Sources said agents and police are attempting to determine the identities of the victims on the videotapes.

Based on the person's claims, FBI agents searched Calamia's Floral Park home Monday and found the tapes, the papers said.

The agents also found online "chats" stored on Calamia's computer in which he discusses meeting with boys who say they are 14 to 16 years old for the purposes of sexual conduct, the papers said.

At Calamia's home, a tenant who rents an upstairs apartment from the bar owner, and who did not want to be identified, said she was stunned when she heard about the charges leveled against her landlord.

She said she heard banging on his door between 8 and 9 p.m. Monday.

"They said 'Open up, police!' And they broke his door open and we heard the whole thing," the tenant said. "I can't believe it."

The FBI requests that anyone having information about the case contact the bureau at 212-384-1000.
